Why Apple Is Experiencing Another Growth Spurt

At 41 years old, Apple is a respected elder of the tech industry. But rather than easing slowly into retirement, the company is going through another growth spurt.

On Wednesday, Apple’s stock surged 5 percent to a record high of $157.14 after it reported surprisingly strong financial results. It is now worth $822 billion, more than any other company in the stock market. And that is before it releases a hotly anticipated new lineup of iPhones this fall, on the 10th anniversary of the original model. Analysts say the new phones could drive sales up by more than 10 percent next year.
